FAQs:

• Is opaque black acrylic good for laser cutting? Yes, it cuts cleanly with CO2 or diode lasers at low power, producing smooth, glossy edges for detailed designs like signs or decals.

• Can I use this outdoors? Yes, cast acrylic is UV-stable and weather-resistant for indoor and limited outdoor use, but prolonged exposure to moisture may require sealing for longevity.

• Is it safe for school projects? Yes, acrylic is non-toxic and safe for general use, but ensure proper ventilation when laser cutting due to fumes. It is not food-safe unless specifically certified.

• Can I paint or engrave it? Yes, the surface can be painted with acrylic-compatible paints or engraved with lasers for custom designs. 

• Can I use a diode laser? Yes, diode lasers can engrave and cut thinner sheets (e.g., 1/16" or 1/8") with multiple passes. Check your laser’s manual for settings.

• How does this differ from extruded acrylic? Cast acrylic is stronger, more resistant to cracking, and cuts with glossier edges compared to extruded acrylic, making it ideal for laser cutting and high-quality projects.
